AUTOMOBILE-BRUSH.

v improvements in brushes especially adapted Yfor `washing mud, .gritand vdust from automobiles or other articles having highly polishedpaint thereomand has for its primary object the provision of a device ofthe above stated character which will loosen foreign matter from -apainted surface and remove the same with a flow of clean water so as toobviate scratching or otherwise'injuring the painted surface.

A further object of this invention is the provision of a mounting forthe cleaning elements, which will form an efficient means for thehandlin'gof the device and alsopermits of said device to be readily andquickly applied to a hose.

A still further objectvof this invention is the provision of a brushl ofthe above'stated character which will be simple, durable and i eiicient,and which may bey manufactured and sold at a comparatively low cost.

With these and other objects in view as will become more apparent as thedescription proceeds, the invention consists y'in cero ment-s within theholder,

tles 4 constructedpfrom comparatively softY h air or 'material' andwhich project outwardly of the casing kfor the purpose of en- Arotatable cleaning element 5 is located within the casing and' alsowithin'the head 3 of the stationary cleaning element 2-and .consistsof ahead 6 of circular formation and has secured to one face a plurality oftufts of bristles 7 which are of a very soft nature. The head 6 isprovided with a centrally arranged opening 8 and each face of the headsurrounding said opening 8 is provided withbearing plates 9. The bearingplates 9 are secured to the head 6 by fasteners 10. A spindle 11 hasformed upon one end ahead 12 provided with arms 13 that are secured tothe top wall'of the casing 1 by fasteners 14 and said spindle extendsdownwardly through the opening 8 of the head 6. A nut and washer ispositioned on the free end ofthe spindle for the purpose of retainingthe head 6 thereon and to permit the cleaning lelements 5 to vhave freerotation within the casing and within the stationary cleaning element 2.

A band 15 is secured to the periphery of the head 6 and has ysecuredthereto a plurality of radially' extending fins or'plates 16, the free`ends of which terminate in close proximity to the side of the casing 1.nozzle 17 is formed on the casing 1. and extends from the casing in aninclinedplane and hascomrnunication with the interior of said casing sothat water injected into said nozzle from a hose 1S will strike againstthe' Specification of Letters Patent. f Patented Oct. 4, 1921.V l

and its outer end receives an ordinary nozzle on the endof the hose 18.

said nozzle and has its outer end cut away t0 the handle for the purposeof preventing said hose from coming in contact with the surface on whichthe brush 1s operating.

A protecting element 22 constructed from rubber or any other materialsuitable for the purpose is of a corresponding shape to the casing 1 and'is placed over the casing and is provided with cut out portions 23 toreceive the nozzle and the handle. The protecting element'22 isadaptedfto prevent the casing from coming in contact with the article onwhich the brush is operating thereby obviating any danger of the casingscratching or marring the surface of said article.

The water passing ,into the casing from the hose strikes againstthe finsrotating the cleaning element 5 withinV the stationary cleaning element2 and the water saturates the bristles of the cleaning element 5 andpasses onto the surface of the article being scrubbed or washed, therebyremoving foreign' matter from the surface of the article thatl has beenloosened by the rotation of the cleaning element 5. The bristles of thestationary cleaning element 2 confine the water and prevents the samefrom being thrown by centrifugal force over too large an area.

`IVhile I have lshownl and described the preferred embodiment of myinvention, it will be understood that minor changes in vrconstruction,combination, and arrangement of parts may be made without departing fromthe spiritand scope of the invention as claimed.

I-Iaving thus described my invention what I claim is z- V A brushcomprising a casing, a station? ary cleaning element carried by saidcasing,

a rotatable cleaning element carried by said j casing, a nozzle carriedby said casing and arranged 'at the inclination to the casing, finscarried by the rotatable cleaning element, a
